Seed Type

Seed type classification refers to whether cannabis seeds are regular, feminized, or autoflowering—fundamental distinctions in breeding programs and cultivation genetics. Regular seeds produce approximately 50% male and 50% female plants, reflecting natural genetic ratios; breeders rely on regular seeds for creating new crosses and selecting breeding stock. Feminized seeds are bred to eliminate male chromosomes, producing only female plants through techniques like colloidal silver or rodelization, streamlining production-focused cultivation. Autoflowering seeds carry genetics from Cannabis ruderalis subspecies, triggering flowering by age rather than photoperiod, enabling faster crop cycles. Understanding seed type is essential for breeders developing stable lines, maintaining genetic diversity, and matching plant material to cultivation environments and breeding objectives.

Breeders select seed type based on breeding strategy: regular seeds enable population-level selection and hybrid vigor studies, feminized seeds accelerate line stabilization and reduce resource waste on males, and autoflowering genetics introduce flowering speed into new crosses or suit specific photoperiod conditions. Preservation of regular seed lines remains important for genetic resource banki
